wddx_serialize_vars - Serialize variables into a WDDX packet

SYNOPSIS

       string wddx_serialize_vars (mixed  $var_name, [mixed  $...])

DESCRIPTION

	Creates a WDDX packet with a structure that contains the serialized representation of the passed variables.

PARAMETERS

	This function takes a variable number of parameters.

	      o $var_name
		- Can be either a string naming a variable or an array containing strings naming the variables or another array, etc.

	      o $...
		-

RETURN VALUES

	Returns the WDDX packet, or FALSE on error.

EXAMPLES

       Example #1

	      wddx_serialize_vars(3) example

	      <?php
	      $a = 1;
	      $b = 5.5;
	      $c = array("blue", "orange", "violet");
	      $d = "colors";

	      $clvars = array("c", "d");
	      echo wddx_serialize_vars("a", "b", $clvars);
	      ?>

	      The above example will output:

	      <wddxPacket version='1.0'><header/><data><struct><var name='a'><number>1</number></var>
	      <var name='b'><number>5.5</number></var><var name='c'><array length='3'>
	      <string>blue</string><string>orange</string><string>violet</string></array></var>
	      <var name='d'><string>colors</string></var></struct></data></wddxPacket>

IS_SCALAR(3)								 1							      IS_SCALAR(3)

is_scalar - Finds whether a variable is a scalar

SYNOPSIS

       bool is_scalar (mixed  $var)

DESCRIPTION

	Finds whether the given variable is a scalar.

	Scalar variables are those containing an integer, float, string or boolean. Types array, object and resource are not scalar.

       Note

	      is_scalar(3)  does  not  consider resource type values to be scalar as resources are abstract datatypes which are currently based on
	      integers. This implementation detail should not be relied upon, as it may change.

       Note

	      is_scalar(3) does not consider NULL to be scalar.

PARAMETERS

	      o $var
		- The variable being evaluated.

RETURN VALUES

	Returns TRUE if $var is a scalar, FALSE otherwise.

EXAMPLES

       Example #1

	      is_scalar(3) example

	      <?php
	      function show_var($var)
	      {
		  if (is_scalar($var)) {
		      echo $var;
		  } else {
		      var_dump($var);
		  }
	      }
	      $pi = 3.1416;
	      $proteins = array("hemoglobin", "cytochrome c oxidase", "ferredoxin");

	      show_var($pi);
	      show_var($proteins)

	      ?>

	      The above example will output:

	      3.1416
	      array(3) {
		[0]=>
		string(10) "hemoglobin"
		[1]=>
		string(20) "cytochrome c oxidase"
		[2]=>
		string(10) "ferredoxin"
	      }
